At its rear end the rear section of the gripping member 4t2 'is formed with a polygonal head 17 whereby a wrench may be applied to rotate the drill gripping niember within the tubular member of the chuck. Forward of this head the member 42 is cylindrical in form as at 48, and forward of this inlturn the member 42 is screw threaded as at 49, these screw threads engaging with the internal screw threads 40 on the tubular member 36 as clearly shown in Fig. 2.

Disposed within the recess 39 of each of the tubular members 36 is a bearing sleeve or bushing designated 50 (see Fig. 3).A This bearing sleeve or bushing has the same internal diameter as theexternal*diameter of the portion -lSOf the tubular member 42, and thesame external diameter as the internal diameter of the recess 39. Surroundingtlie extremitj1 of the portion 48 rearward of the bushing 50 is a thrust nut 51 illustrated in Fig. '3. This thrust nut'as shown in the sect-ionalview, Fig. 2, has an A internal diameter -equal tothe external diameter of thev portion '48 of the tubular member 42 and is providedwith a polygonal head 52 and a screw threaded portion 58 whicliis adapted to engage with the internal screw threaded perforations 2O in the cap 16. The head 4T of the tubularmember 42 of course projectstlirough this bushing 5l as illustrated in Fig. 2 so that a wrench may be applied either to the 'head 47 or to the head 52 as 'desired This member 51 bears against the sleeve 50, and by screwing inward onthe'member 51, the bushing or sleeve 50 may be forced forward to bear with more force against the tubular member 36, thus forcing this tubular member to its seat in the collar or bushing 33. By rotating the nut 51 in a reverse direction, the pressure upon the .tubular member may be decreased. For the purpose of holding the nut' 51 in any adjusted position, a lock nut 5l is ap-- plied to the exterior thereof as illustrated in Fig. 2, which lock nut bears against the end of the cap 16.

Supported within eacli of the. tubular drill clamping members 42 is a driltillustrated in Fig. 3 and designated This drill maiy be of any suitable length and of lany s'uitable character. The drills used on this machine are ordinarily very small in diameterand relativel)v long so that they project out. a considerable distaucebevond the extremities of the jaws 45. l

The forward end of the semitubular prolongation 22 of the head 14 is formt-d with a collar 56 upon which is mounted a cap F" perforated at a plurality of points for. .fe passage of -tlie cut-ting extremities of for the extremities of the drills.

'the drills This cap 57has an internal flange 58 which extends into the bore of the collar 56. This 'cap 57 isheld in place by means of a set screw 59 passing through the collar 56. This cap 5 7 constitutes a guide It will be noted that the drills are all inclined forward and toward a common center, and that therefore they would bore perforations through the button which-would also be inclined from .the front to the rear of the button and toward a common-center.y For the purpose ofpreventing this and bending the' flexible drills so that the extremities of the drills shall be parallel with each other. we have provided tliis'cap or guide 57 and form the cap. or guide lwith parallel perforations through which the drills pass. These parallel perforations tend to bend the drills'to a very slight degree fromV an angular relation to each other into a arallel relation.

In order to support 't ie projecting ends of the drill and prevent anyflexing of the drills, we provide a'sliiftable disk 60 which isl perforated for the .passage of the several drills. these perforations being inclined forwardly and centrally with relation to the axis of the disk 60. The shell VJforming the prolongation 22 i longitudinally slotted as at 61 an'd the disk is attached t0 a plate 62 adjustably disposed upon tlie exterior of the prolongation 22,. this disk passin through theslot 61. The plate 62 is longitudinally slotted as at 63 and engages with a fixed binding screw 6l which is mounted upon the wall of the pro longation 22 and extends o'ut through the slot 63 and is provided with a nut 65. lt will be seen that this construction permits Aas to secure a proper bearing and support for the drills 55.

For the purpose of gaging ,the drills 55 so as to bring their cutting ends all into one plane, we provide the slidable gage 66 which is mounted in a barrel 67 formed upon tlie extension 22. This gage consists of a rod which passes through the .barrel 6T and 'which vat its extremitvy is aiigularl)Y lient as at 68. this angularly bent end carrying a fiattened terminal portion 69 which is adapted to be placed immediatelyY in front of the openings through the guide 5l' so that the drills majY b e shifted until their extremities come in contact with the flattened terminal end 69. ll'lien the drills are thus adjusted so that their extremities are'all in one plane, the guide. is then turned up as shown in dotted lilies in Fig. 2. The guide bai- 66 is provided with a' stop 'T0 preventing the withdra-wal of thcguidc hejiond a certain point. and gaging the distance ot t terminal end Il() 69 with relation to lne face of the guide 5T. While we do not wish lo he limited to any the disk 60 to be adjusted longitudinally so# 105@v .particular means 'for mounting the drill head, ive-.have shown as before stated, thea tubular portion 14 as being mounted upon fapost 15. As illustrated in Fig. 2, this post `.ing flange .l

is formed `with a central cylindrical depending portion 7-1 supported within a-,socketlike'sleeve .71L having an outwardly project-- 2 at its upper margin. .This, socket-like member 71a rests Within the hollow upper end of a b`ase73 which isprovidedat one side with av projecting lug 74 having a screw `threaded passage passing therethrough. Themember 71 is also provided with an' outwardly 'projecting screvv threaded lug 7 5, and passing .through both of these lugsis a screw 76 formed with a median -head f77-'disposed between the lugs 74 and 7 5 and whereby- `the'socket member 71 with the post limay be raised or" lowered 'and 'thus the drill head adjusted-vertically.

After its adjustment,'thedrill head may' be .held in any desired permanently 4adjusted position by means of a set screw .78 provided with ahandle 79.- L l The operation of our invention is as follou's The drillshaving been adjusted, and a but-tonplaced withinthe but-ton chuck 9,

power is applied tothe internal -geir 23 by the pulley 28. As the internal' gea rotates -in one direction, it will rotate the several drill chucks, and as vthe button is moved forward against the extremities of tlie drills,

the button will be perforated. At' any time' the bearings for any one of the several drill chucks ma y, be adjusted by rotating the nuts `Whcii these nuts are rotated inward,

' .they bear against the collar or bushing 50, and this in turn bears against'the head-3S h the-head1@ ofthe drill chuck 36, -forcing the chuck forward more firmly into the seat formed in the collar 83. ABy engaging thehead 47 of the chuck member 42, the aivs may be tightened or loosened upon the drill, the jaws' being loosened topermit the drill to be adjusted Within the jaws and tightened after the drill is adjusted. it will be obvious that by removing the nut the bearing coll-ar 5() may be removed or replaced, and that the entire chuck may be Withdrawn from therear end of the iii'achine,'tlie bushing-24 holding the internal gear 23 and the Abushings 3l and 32 in place. -l`5y removing the cap 1G, it is possible to remove the bushings'24 rand 32, the sleeve 23 and the thimble 33 so that: the part-s may be repaired or replaced.
